T50.0 — Poisoning by, adverse effect of and underdosing of mineralocorticoids and their antagonists
T50.0 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of mineralocorticoids and their antagonists. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category T50
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Other codes that can never be billed with T50.0
These codes carry an Excludes1 note pointing at T50.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T50.0 alone.
- T38Poisoning by, adverse effect of and underdosing of hormones and their synthetic substitutes and antagonists, not elsewhere classified
Risk adjustment
T50.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead T50.0
1 child code. Green means billable.
